CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 297,657, dated April 29, 1884.

Application filed October 29, 1883. (No model.)

To all whom, it may concern:

Be it known that I, DANIEL ARCHER, a citi zen of the United States, residing in Madison, county of Yolo, and State of California, have made and invented certain new and useful Improvements in Orchard and Vineyard Cultivators; and I do hereby declare that the folof the same.

My invention relates to an improved farming implement of the kind commonly termed Cultivators, and the object sought to be attained is to produce in a simple form and at a low cost of manufacture a cultivator having features that render it particularly serviceable for orchard, vineyard, and other close work.

The nature of my improvements and the manner in which I proceed to construct, produce, combine, and carry out the same are set forth in the following description and shown in the accompanying drawings, to which reference is made by figures and letters, Figure 1 being an elevation, and Fig. 2 a plan or top View, of a cultivator embracing my improvements.

A is a draft-beam, provided with the usual clevis -connection, 1?, for the animal on the front end, and at the rear a pair of guide-handles, O C, properly braced and bolted.

At intermediate points in the length of the beam are fixed two crossarms, D D, at right angles to the beam and parallel with each other. These arms pass under the beam and outer ends two shifting beams, B B-one. on each side of the draft-beamand the attachment is of such character that the beams 13, extending across the arms D and in a longitudinal direction, can be shifted laterally upon the arms to change the distance between the points or shares carried by the beams. I form such a fastening by letting the ends of the bars D through slots in the beams, and then passing bolts or pins m from the top through the beams and the bars, a series of holes, a n, being provided in the outer portion of each bar to allow the beams to be shifted. These parts A B B D D constitute a frame capable of being adjusted to work in different widths or spaces between rows.

The shares or points are flat plates or soles,

E, fixed on the ends of standards E, that consist of metal bars set edgewise, or with their edges in the direction of travel. Their upper ends or shanks pass through slots in thebeams, and are secured by through-bolts c c. The soles E have a slight dip or inclination forward, and they are set at right angles to the face of the standards, so that they project i11- wardly toward the center of the frame. Their points are curved and their front edges beveled fromheel to point. The center beam carries a standard, F, provided with a flat share, f, that is set to work in advance of the shares E and on the line of the center of the frame. The standard is fixed in the center beam by a through-bolt, e", and at a point beable vertically to vary this penetration, ac-

cording to the character of work to be done. The axle of the wheel is a tube of a length equal to the space between the curved hangersJ J, and a short rod passing through the sides of the hangers and through the tube forms the center for the wheel. The straps I I, that embrace the beam A, have eyes in the lower ends .to receive bolts j, which serve to secure the hangers to the straps. A set of holes, 7', are provided in the ends of the hangers at distances apart, so that the'bolts can be shifted up or down and the height of the wheel changed accordingly. A rake or harrow attachment is fixed to the rear end of the frame, for leveling and smoothing the surface after the cultivator-shares have acted upon it. This attachment is arranged to be thrown into and out of operation as desired, and it is formed of a V- shape frame composed of two bars,G G, attached at the-outer ends to the standards E, and united at the opposite ends,

where a suspension-rod, h, is connected by a swivel-joint. The upper end of the rod is hooked to engage with a cross-rod fixed between the handles G, and the rear end of the frame G is supported in a substantially horizontal position, or it is raised up out of contact with the ground beneath. The bars G are armed with teeth They are also attached by a loose joint to the standards to allow of vertical movement, and the rear ends are jointed in the same manner, so that the two bars G may move with the standards E as the beams B are shifted.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a cultivator, the combination of the draw-beam A and cross-pieces D D, movable side bars, 13, and means for adjusting them to and from the draw-beam, shares E, secured to the side bars, with a central share, f, secured in front of the shares E to the drawbeam, substantially as herein set forth.

2. In a cultivator, the combination, with the draw-beam and frame, of the upright standards E, bearing the shares, and the horizontal bars G, having the harrow-teeth g 9, said sup-
